ROLLER-BEARING.

Specification of Letters Patent.

Application filed September 19, 1912, Seria1 No. 721,233. Renewed December 1, 191 5. Serial No. 64,582.

To all whom it may concern Be it known that I,'J0HN A. CRAIG, a citizen of the -United' States, residing at Johnsonburg, in the county of Elk, State of Pennsylvania, have invented certain new and useful Improvements in Roller-Bearings; and I do hereby declare the following to be a full, clear, and exact description of which is so constructed that the parts may be readily assembled or disassembled-and which, when in the former position, will include an oil receptacle for containing the bearing roller.

Another ob ect of the invention is to provide a roller bearing of the character de-.

scribed which is composed of a minimum number of parts, is therefore simple in 0on9 struction and is cheap to manufacture.

With these and other objects in view, the

invention consists in the construction and novel combination of parts hereinafter fully described, illustrated'in the accompanying drawings and pointed out in the claims hereto appended; it being understood that vari ous changes in the form, proportion, size and minor details of construction within the scope of the claims may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

In" the drawings: Figure 1 is a side elevation of abearing constructed in accordance with my inventlon, Fig. 2 is an end view thereof, Fig. 3 is a. vertical sectional view taken on the line 3-3 of Fig. 1, Fig. 4 is a cross sectional view taken on the line 4-4 of Fig. 2, Fig. 5 is a cross sectionalview taken on the '1ine;5 -5'of Fig. 2, Fig. 6 is a perspective view of the detachable cap,

Fig. 7 is a cross sectional view taken through one of the bracket arms taken ontheline 7-7 of Fig. 1, and Fig. 8 is aperspective 7 view of the bushing.

Like reference numerals designatecorredrawings.

sponding parts in all the figures of the which is disposed against the outer face of each arm 6 and is secured to said armby means ofbolts 12 -12. This plate closes the recess 8, andis pressed inwardly to form a bearing 13 arranged concentric with the recess 8. Extending inwardly from the plate 11 around the bearing 13 is an annular rib 14 which constitutes a circular bearing. The lower end of the plate is formed with an inwardly extending semi-circular flange 11, the ends 1515 thereof being disposed in opposed and in spaced relation to the shoulders 9 of the arm 6.

The recess 8 and flange 11 conjointly form a seat for receiving an annular bushing 16, and this bushing is formed on its inner edge with an inwardly extending flange 17.

Extending outwardly from the bushing at diametrically opposite points are transverse lugs 1818 which are respectively seated between the shoulders 9 and the ends 15 of the flange 11. As a result, the bushing 16 is interlocked by means of the lugs 18 between the arms 6 and the cap 10 in such a manner as to prevent rotation of said bushing. An

axle 19 has its ends respectively extending through the flange 17 of the bushing 16, and has its extreme ends operating against the bearing 13 of the caps 10. Disposed around the axle l9 and the bushing 16 1s a plurality of bearing rollers 20, said. rollers having their ends operating intermediate the annular bearing 14 of the cap 10 and the mwardly extending flange 17 of the bush- I ing 16. I

Formed in the cap 10 is arr'opening 21 which communicates withthe bearing rollers 20, and mounted in this opening is a spring actuatedfvalve 22 which will normally remain seated and yet permit of the operator readily oiling the rollers whenever necessary.

Mounted on the axle 19 intermediate the bushing 16 of the arms 6 is the hub 23 of a wheel 24.

In practice, it willbe observed that the flanges 11 of the plate 10 serve to support the bushing upon the lower end of a respective arm 6, and that the bushing inturn is interlocked against rotation between the arm and the plate, and that this bushing is .of, an annular bushing located in each of ture, in presence of two witnesses.

' itieasae said recesses and having outwardly extending flanges thereon enga 'ng the lower ends of the said legs, the sald bushings havingflanges on the inner ends thereof, a plurality of bearing rollers mounted in said bushings, a cap detachably secured to the lower end of each of said legs, the said cap having circular grooves on their inner faces in which the outer ends of the said bushings are located, and an axle extending between said bushings and mounted between the rollers therein, the said caps having inwardly extending substantially convex portions located in such manner as to bear against the ends of the axle to thereof.

In testimony whereof, I aflix prevent end thrust my signa- JOHN A. CRAIG.
